Abstract

A method and apparatus for destratifying heat within an enclosure wherein a fan is positioned near the ceiling to draw warm air off the ceiling propelling same along a distribution tube also located near the ceiling and wherein the tube is provided with a plurality of openings along the bottom thereof through which the warm air is discharged toward the floor of the enclosure in the form of high velocity jets which entrain large quantities of surrounding ceiling air moving same to the vicinity of the floor of the enclosure.

Claims

1. A method of destratifying heat within an enclosure, comprising:

drawing warm inside air off of the ceiling of the enclosure,

propelling the warm inside air from the ceiling along a confined path that is separate from the remaining portions of the air within the enclosure,

jetting the warm air downwardly from the confined path along a plurality of streams to the vicinity of the floor of the enclosure, and

entraining quantities of surrounding warm air by the downward movement of each of the jetting streams thereby moving the surrounding warm air to the vicinity of the floor of the enclosure.

2. A method of destratifying heat within an enclosure as in claim 1, wherein the ratio of air propelled along the confined path to the air entrained by the jetting streams is in the approximate range one to ten.

3. A method of destratifying heat within an enclosure as in claim 1, wherein said confined path is located generally horizontally in the vicinity of the ceiling of the enclosure such that the warm air collected off the ceiling of the enclosure is jetted downwardly through-out the large mass of warm air located throughout the uppermost regions of the enclosure, and wherein the plurality of streams lie in vertically positioned planes intersecting the axis of said path at right angles and spaced uniformly along the axis of said path.

4. A heat destratification system for an enclosure, comprising a fan positioned near the ceiling of the enclosure to draw warm inside air off the ceiling of the enclosure, a distribution tube also located near the ceiling of the enclosure and connected to the discharge of the fan through which the warm air is propelled, and a plurality of openings along the bottom of the distribution tube through which the warm air is discharged to the vicinity of the floor of the enclosure in the form of high velocity jets of primary air which entrain large quantities of surrounding warm ceiling air moving same as secondary air to the vicinity of the floor of the enclosure.

5. A heat destratification system as in claim 4, wherein said openings are uniformly spaced along said distribution tube and are of a size such that the jets of primary warm air being discharged therethrough utilize most of their kinetic energy for mixing with a small residual velocity at the vicinity of the floor of the enclosure.

6. A heat destratification system as in claim 5, wherein said tube is of non-rigid material, air pressure from said fan holding said tube in its contemplated shape during use.

7. A heat destratification system as in claim 5, including means defining a ratio of approximately one to ten between the amount of primary air propelled downwardly through said openings in said tube to the vicinity of the floor and the amount of secondary surrounding warm air entrained by the primary air and moved to the vicinity of the floor.
